For example, in an embodiment of the present invention, a network device may periodically determine and transmit transmission resources for beam group #1. That is, in embodiments of the present invention, the time domain resources used in the communication system may be divided into multiple periods. A network device may determine transmission resources for beam group #1 at some point in each period (eg, at the beginning of the period) and transmit.

Also, for example, if the number of terminal devices within the coverage of one or more beams included in beam group #1 decreases, the network device needs to re-determine transmission resources for beam group #1 and transmit can be determined.

Specifically, when the number of terminal devices within the coverage of one or more beams included in beam group #1 is reduced to less than a predetermined number threshold #C, the network device transmits beam group #1. It can be determined that the resource needs to be re-determined and sent.

Alternatively, if the decrease value Δ#B of the number of terminal devices within the coverage of one or more beams included in beam group #1 is greater than or equal to a predetermined number threshold #D, the network device transmits beam group #1. It can be determined that the resource needs to be re-determined and sent.

Parameter #2: The amount of service that needs to be transmitted on the beams included in beam group #1.

For example, if the service volume of the service that needs to be transmitted in the beams included in beam group #1 increases, the network device determines that the transmission resources of beam group #1 need to be re-determined and transmitted. be able to.

Specifically, when the service amount of the service that needs to be transmitted by the beams included in beam group #1 increases and exceeds a predetermined number threshold #E, the network device reallocates the transmission resources of beam group #1. You can confirm that you need to confirm and send.

Alternatively, when the increase value Δ#C of the service amount of the service that needs to be transmitted by the beams included in beam group #1 is equal to or greater than a predetermined number threshold #F, the network device uses the transmission resource of beam group #1. It can be confirmed that it needs to be confirmed and sent again.

Also, for example, when the service amount of the service that needs to be transmitted by the beams included in beam group #1 decreases, the network device needs to re-determine the transmission resources of beam group #1 for transmission. can be determined.

Specifically, when the service amount of the service that needs to be transmitted by the beams included in beam group #1 decreases and is less than a predetermined number threshold #G, the network device uses the transmission resources of beam group #1. It can be confirmed that it needs to be confirmed and sent again.

Alternatively, when the decrease value Δ#D of the service amount of the service that needs to be transmitted by the beams included in beam group #1 is equal to or greater than a predetermined number threshold value #H, the network device uses the transmission resource of beam group #1. It can be confirmed that it needs to be confirmed and sent again.

Parameter #3: Service type of the services that need to be transmitted on the beams included in beam group #1.

For example, if the service type of a service that needs to be transmitted in one or more beams included in beam group #i changes, the network device needs to re-determine transmission resources for beam group #1 and transmit. It is possible to ascertain that there is

In some cases, based on the number #α, the network device selects transmission resources (e.g., time domain resources or frequency domain resource), and based on the estimated size of the transmission resource, determine the size of the transmission resource of beam group #1, for example, the network device can estimate the size of the transmission resource of beam group #1. The size can be close to the estimated transmission resource size, specifically, the network device determines that the difference between the transmission resource size of beam group #1 and the estimated transmission resource size is less than or equal to a preset difference threshold. can be
